A sparklefraffle is a hideous pain in your wrist. Sparklefraffles occur when you have typed too much, when you have 4 pets or more and you have to pet all of them or when you masturbate longer than 78.5 minutes.
Sparklefraffles appear suddenly, often in the morning and they last from two hours up to two days.

June: "No, I can't type, I have this sparklefraffle in my left wrist."
